On page 5, the paper mentions that RULES pragmas in an imported module
may change the meaning of the importing module. This is true. However,
I see another problem: RULES pragmas in the imported module can make the
code in the imported and the importing module non-deterministic, as it
is not clear which rules are fired. Is there a reason for this problem
not being mentioned in the paper? Or am I understanding something wrong?
Best wishes,
